EurekaUser-MybatisPlus

CREATE TABLE `user` (
  `id` bigint(20) NOT NULL COMMENT '主键ID',
  `name` varchar(30) DEFAULT NULL COMMENT '姓名',
  `age` int(11) DEFAULT NULL COMMENT '年龄',
  `email` varchar(50) DEFAULT NULL COMMENT '邮箱',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

 建表语句，创建后随便添加几条数据

创建Spring Initializr项目

选择Eureka Discovery Client

 配置maven

 刷新jar包

 配置文件application.properties配置如下

server.port=10001
spring.application.name=eureka-user
#注册的eureka.Service信息
eureka.client.serviceUrl.defaultZone=http://127.0.0.1:8761/eureka/
#注册成ip
#spring cloud不同版本的配置可能不同，比较老的版本是eureka.instance.preferIpAddress=true
#不行的话需要配置eureka.instance.instanceId
eureka.instance.preferIpAddress=true
spring.cloud.client.ipAddress=127.0.0.1
eureka.instance.instanceId=${spring.cloud.client.ipAddress}:${spring.application.name}:${server.port}
#################mysql#################
#指定时区和编码
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/lianxi?characterEncoding=UTF-8&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
#mybatis-plus 开启SQL语句打印
mybatis-plus.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl

　　启动类

@EnableEurekaClient
@SpringBootApplication
public class EurekaUserApplication {

    public static void main(String[] args) {
        SpringApplication.run(EurekaUserApplication.class, args);
    }

}

　　UserMapper

@Mapper
public interface UserMapper extends BaseMapper<User> {

}

　　User

@Data
public class User implements Serializable {
    /**
     */
    private Integer id;

    /**
     */
    private String name;

    /**
     */
    private String age;

    private String email;

}

　　UserAction

@RestController
@RequestMapping("/user")
public class UserAction {


    @Value("${server.port}")
    String port;

    @Resource
    private UserMapper userMapper;

    @RequestMapping("/hi")
    public String hi(@RequestParam String name) {

        System.out.println(("----- selectAll method test ------"));
        List<User> userList = userMapper.selectList(null);
        userList.forEach(System.out::println);

        return "hi " + name + ",i am from port:" + port;
    }

}

　　

　　启动项目访问

http://127.0.0.1:10001/user/hi?name=ok

 启动项目可能会报lombok找不到，这时需要把maven里的<localRepository>配置注释掉。idea2020.01无法识别自行设置的localRepository ，所以启动的时候去默认.m2去找jar包，maven下载的包在配置的目录下导致找不到。
